Is CT or US better for diagnosing gallbladder infection?
July 30, 2018 -- CT was found to be considerably more accurate than ultrasound at identifying acute cholecystitis in a new study, published in the August issue of the American Journal of Roentgenology. But is that enough evidence for CT to oust ultrasound as the imaging modality of choice? Probably not, say researchers from New Mexico. Read More
3D-printed breast phantoms help refine mammography
July 30, 2018 -- Researchers from Maryland have developed new 3D printing software for creating patient-specific 3D-printed breast phantoms that could help enhance the evaluation of mammography devices, according to an article published in the July issue of the Journal of Medical Imaging. Read More
Shear-wave elastography works to evaluate liver disease
July 30, 2018 -- Two-dimensional shear-wave elastography is an effective tool for identifying cirrhosis, according to a study by researchers from China and published online July 24 in Radiology. The technique could offer a less invasive alternative than the current practice of liver biopsy. Read More
#MyRadGirlfriend No. 68: The last straw
July 27, 2018 -- What's the deal with plastic straws, anyway, and why have they suddenly become public enemy No. 1? Ryan asks this question to Andy and gets more information than he bargained for in the next installment of #MyRadGirlfriend. Read More
Breast density notification laws boost ultrasound use

U.K. research could lead to flexible x-ray detectors
July 27, 2018 -- What if x-ray detectors were flexible enough to conform to patient anatomy? Would they produce better image quality or enable more accurate monitoring of radiation dose? It may not be a pipe dream. Researchers from the University of Surrey in the U.K. are working on a digital x-ray detector material that could be fabricated into flexible x-ray detectors. Read More
CMS proposes 'site-neutral' payments for outpatient, hospital clinic visits
July 26, 2018 -- Healthcare providers would be paid the same by Medicare for clinic visits regardless of whether the service took place in a hospital or an outpatient setting under a proposal for site-neutral payments issued July 25 by the U.S. Centers for Medicare and Medicaid Services (CMS).

VR software may increase MRI segmentation efficiency
July 26, 2018 -- Using new virtual reality (VR) software to correct segmentation errors on MRI scans allowed users to complete the task more quickly and accurately compared with using a conventional 2D interface in a new study, published online July 20 in the Journal of Digital Imaging. Read More
fMRI links key brain regions between sleep and depression
July 26, 2018 -- Functional MRI (fMRI) scans have helped open researchers' eyes to which brain regions provide the primary connections and associations between poor sleep quality and depression, according to a study published online July 25 in JAMA Psychiatry. Read More
CAD software speeds up ABUS interpretations
July 26, 2018 -- Computer-aided detection (CAD) software based on deep-learning technology can significantly reduce interpretation times for screening automated breast ultrasound (ABUS) studies without negatively affecting accuracy, according to research published in the August issue of the American Journal of Roentgenology.
